Alright guys, I've kept fish off an on for the last ten years or so, and want to get some established systems going. I have one 29 gallon saltwater I'm doing, and have an empty 55 sitting in my living room. I've looked at cichlids, but I'm worried their breeding habits/maintanence requirements will be a little too much for me. I've thought about regular tropical communities, but I want to do something a little more unique. Any ideas for specific habitats or just a stocking list of generic oddballs? I think a predator tank would be fun, but I'm not sure if a 55 is big enough, with only the 12" depth? Thanks guys!
